HelloPharmacist Scorecard of Black Currant Extract by Herbadiet

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 16, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: black currant fruit extract. Black currant comes from a berry plant and has been studied for potential effects on several health conditions.

The capsule itself is made from vegetable cellulose, an inert shell.

Does it work?

Not established
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Black Currant's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: immune system, eye health, gut and kidney health.
  • We looked for evidence on: Common cold, Dry eye, Influenza, Upper respiratory tract infection (URTI), Atopic dermatitis (eczema), Conjunctivitis — and 2 related terms.
  • The closest evidence on file: Black Currant is rated "Insufficient Reliable Evidence To Rate" for Upper respiratory tract infection (URTI) (Natural Medicines).
  • Also on file: Black Currant is rated "Insufficient Reliable Evidence To Rate" for Atopic dermatitis (eczema), Dry eye, Influenza, Common cold.

The evidence on black currant extract for the conditions it's marketed for—including Alzheimer disease, liver disease, upper respiratory infections, cough, and eczema—is currently insufficient to rate. We don't have strong data showing it works for any of these uses yet.

The evidence, ingredient by ingredient Black Currant

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

The black currant berry is safe to eat as food, but concentrated supplements like this one haven't been studied as thoroughly. The safety data we have is limited, so caution is warranted.

In one trial of 2,154 people taking black currant seed oil at a higher dose for 6 weeks, a small number reported mild diarrhea a few days after starting. There's no information on file about safety during pregnancy or breastfeeding, so talk with your doctor before using this product if you're pregnant or nursing.

Side effects, ingredient by ingredient Black Currant

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Black Currant.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 140 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, double-check with your doctor or pharmacist if you take anticoagulants or antiplatelet drugs—blood thinners like warfarin, aspirin, or clopidogrel—because black currant may increase bleeding risk. Also clear it with your provider if you're on phenothiazines (certain psychiatric medications), since there's a theoretical concern about lowering seizure threshold.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Black currant extract may be worth considering if you're interested in supplements for conditions like respiratory health or skin concerns, but the evidence for effectiveness isn't established yet. If you take blood thinners or psychiatric medications, this product needs a conversation with your own doctor or pharmacist first.

Also check with them about safety during pregnancy or breastfeeding before starting.

Black Currant Fruit Extract2 drug types · 140 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, black currant seed oil might increase the risk of bleeding if used in combination with anticoagulant or antiplatelet drugs.
Gamma-linolenic acid (GLA), a constituent of black currant seed oil, appears to have antiplatelet effects.

Likelihood Possible Evidence D
Phenothiazines

Theoretically, black currant seed oil might increase the risk of seizure in patients receiving phenothiazines.
Black currant seed oil contains gamma-linolenic acid (GLA). There is some concern that taking supplements containing GLA might cause seizures, or lower the seizure threshold, when taken with phenothiazines, although there is no evidence that black currant seed oil causes seizures. In one report, three patients with schizophrenia who had received phenothiazines developed EEG changes suggestive of temporal lobe epilepsy after starting treatment with GLA, although none experienced an actual seizure. In another report, two patients with schizophrenia who were stabilized on phenothiazines developed seizures when evening primrose 4 grams daily, which contains GLA, was added. One of these patients had a prior history of seizures.

Black Currant Extract by Herbadiet: Common Questions

Does Black Currant Extract by Herbadiet interact with any medications?
Yes. Based on its ingredients, Black Currant Extract has a known interaction with 140 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Black Currant Extract contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take black currant extract if I'm on a blood thinner?
Not without checking first. Black currant seed oil may increase your bleeding risk if combined with anticoagulants like warfarin or antiplatelet drugs like aspirin. Talk with your doctor or pharmacist before starting this product.
What side effects might I see?
In a large study, a small number of people reported mild diarrhea a few days after beginning the supplement. Otherwise, side-effect data is limited because concentrated supplements haven't been studied as much as the food form.
Is this safe to take while pregnant or nursing?
There isn't enough information on file to know whether black currant extract is safe during pregnancy or breastfeeding. Talk with your doctor before using it if you're pregnant or nursing to see what's right for you.
Does black currant extract actually work for respiratory infections or cough?
The evidence isn't strong enough to rate it yet. We don't have reliable data showing it helps with cough, upper respiratory infections, or the other conditions mentioned.
What's the difference between black currant berries and black currant extract?
The berry itself, eaten as food, is safe. This product is a concentrated supplement, which hasn't been studied as thoroughly, so it needs more caution and a conversation with your provider before starting.
